Child swing with remote battery compartment

Description

Field of the invention

[0001] The present invention relates generally to a motor driven infant swing and, more particularly, to a remote battery compartment supported on the swing frame to locate the batteries away from an infant positioned on the swing seat.

Background of the invention

[0002] Baby swings are used extensively by infant caregivers to soothe and to comfort the children. An infant swing consists primarily of a seat that securely holds the infant in a position elevated off the floor and a frame apparatus that supports the seat and allows the seat to move in a reciprocal manner, typically in a forward and rearward direction though some infant seats provide a side to side swinging motion.

[0003] The first infant swings consisted of a seat suspended from a frame that was formed with a support structure that extended over top of the infant and was supported by transversely opposed support legs that hold the overhead support structure in the elevated position. This overhead support structure restricted access to the child positioned in the seat as the support structure presented a physical barrier directly above the child. Such an infant swing can be seen in U. S. Design Patent No. D345,777, issued on April 4, 1994, to Daniel Pinch, et al. Not only is the overhead support structure a barrier to accessing the child in the swing from above the child, but the support structure also presented a barrier to viewing the infant.

[0004] As a solution to the barrier presented by the overhead support structure, the "open top" infant swing was developed. As can be seen in U. S. Patent No. 4,822,033, issued to Louis Kohus and James Mariol on April 18, 1989, the overhead structural support has been eliminated to provide an open access to the child in the seat from above. However, the child can be capable of grasping either of the transversely opposing support legs, particularly as the child is swinging back and forth between the support legs. Contact between the swinging child and one of the support legs can result in injury to the child. Furthermore, the child can potentially grab one of the support legs and pull his or herself forwardly to become dislodged from the seat, particularly if the child has not been properly secured within the seat by a safety harness.

[0005] The aforementioned open top infant swing evolved in a manner to eliminate the frame structure, i.e. the support legs, positioned forwardly of the swinging seat to provide an "open side" swing frame configuration for an infant swing. Such an open side infant swing can be found in the aforementioned U. S. Patent No. 4,822,033, issued to Kohus and Mariol on April 18, 1989. In the Kohus and Mariol patent, the infant swing is provided with both an open top and an open side structural configuration to provide the capability of viewing and accessing the child within the seat from substantially any position forwardly of the seat.

[0006] The swinging motion of most baby swings commercially available is similar to that of a pendulum that pivots from above and to the sides of the seat. Although this swinging motion can be maintained by a mechanical spring-operated swing mechanism, the swinging motion in most modern infant swings is maintained, typically, by a small electric motor located adjacent one of the seat pivots supported by the frame structure. The power for this electric motor is typically an array of dry cell batteries located within the same plastic housing as the electric motor. Examples of battery operated motors to affect the swinging motion of the infant seat from a frame support can be seen in U. S. Patent No. 5,525,113, issued to Daniel Mitchell, et al on June 11, 1996, and in U. S. Patent No. 5,833,545, issued to Daniel Pinch, et al on November 10, 1998.

[0007] Although such an arrangement of placing the dry cell batteries within the same covered housing as the electric motor is convenient for the wiring of the power source to the electric motor, this arrangement has several disadvantages as well. Locating the placement of the dry cell batteries above the swing seat, exposes the child positioned within the seat to being impacted by a dropped battery when the caregiver is forced to change the batteries to replace depleted batteries with fresh ones. Dry cell batteries are manufactured with acid within the battery container. Sometimes that acid can escape from the battery which would also present an injury risk to a child positioned within the seat. The placement of the battery array within the same housing as the electric motor also increases the height of the centre of gravity of the swing, thus increasing the possibility of the swing tipping over. Lastly, since the spatial requirements of an electric motor and battery array are greater than for just the electric motor alone, the size of the housing needed to contain the electric motor and the battery array detracts from the ability to view the child.

Summary of the invention

[0008] With a view to mitigating at least some of the foregoing disadvantages, the present invention provides a child swing having a seat assembly mounted for reciprocal movement, said seat assembly having a top surface, the child swing further comprising a pair of transversely spaced rear legs projecting upwardly and forwardly from a rear support position and terminating at respective elevated distal ends; a pair of transversely spaced front legs extending upwardly and rearwardly from a front support position, said front legs intersecting the corresponding said rear legs at a central region of said rear legs; a mounting housing mounted on each said rear leg at said central region to receive the corresponding said front leg for support thereof; a hanger housing mounted on the distal end of each said rear leg for support of a seat assembly for reciprocal movement thereof in a direction of movement; and an electric motor supported in one of said hanger housings and being operably connected to said seat assembly to power said reciprocal movement thereof; characterised in that a battery compartment is supported in one of said mounting housings located vertically below said top surface of said seat assembly and remotely of said electric motor to retain an array of batteries to provide electrical power to said electric motor.

Detailed description of the preferred embodiment(s)

[0010] Referring now to the drawings, an infant swing having a frame apparatus incorporating the principles of the instant invention can best be seen. The infant swing 10, as can best be seen in Fig. 6, includes as the major components thereof a frame assembly 12, including a pair of transversely spaced rear legs 15 and a corresponding pair of front legs 17, and a seat assembly 20 suspended from the frame assembly 12 for a fore-and-aft swinging movement. The seat assembly 20 is formed of a moulded seat member 22 and a pair of transversely spaced hangers 25 that are connected to corresponding hanger housings 27, 28 positioned at the cantilevered ends of the rear legs 15, as will be described in greater detail below.

[0011] Referring now to Figs. 1 - 6, the frame assembly 12 is formed with a pair of transversely opposing rear legs 15 that extend upwardly and forwardly front a rearward support position with a curvature thereof being concave facing downwardly and forwardly. The rear legs 15 terminate at upper hanger housings 27, 28 at the elevated distal ends thereof. One of the hanger housings 28 is formed to encompass an electric motor 29 that is operable to move the seat assembly 20 in a reciprocal manner in a fore-and-aft direction, as will be described in greater detail below. The curvature of the rear legs 15 provide an aesthetically pleasing shape that positions the hanger housings 27, 28 at an elevated, cantilevered position with no structure immediately below the hanger housings 27, 28.

[0012] A corresponding pair of curved front legs 17 is positioned forwardly of the rear legs 15 in fore-and-aft alignment therewith to extend rearwardly and upwardly from a front support position to intersect with the corresponding rear legs 17 at a central point thereof. Each of the rear legs 15 has mounted thereon at the central point thereof a mounting housing 18, 30 for the connection of the corresponding front leg 17 by a quick connect mechanism 19 that enables the front legs 17 to be detachably connected to the rear legs 17 and removed therefrom to convert the swing 10 into a storage configuration without the use of tools, such as a screwdriver or a wrench. The curvature of the front legs 17 is concave upwardly and forwardly so that the front legs 17 also do not provide any substantial structure beneath the hanger housing s 27, 28. The mating curvatures of the rear legs 15 and the front legs 17 establish an open side configuration of the frame assembly 12 with respect to access to a seat assembly 20 hanging from the hanger housings 27, 28.

[0013] The front legs 17 are interconnected by a moulded front cross brace 14 that preferably has a curved configuration to correlate with the curved front and rear legs 17, 15 and provide an aesthetically pleasing appearance. Similarly, the transversely opposing rear legs 15 are also interconnected by a rear cross brace member 13 to provide a stable support for the suspended seat assembly 20 to resist the forces associated with the fore-and-aft swinging of an infant positioned in the seat assembly 20. The curvature of the moulded front cross brace 14 eliminates the conventional tubular structural member that is positioned between the front legs. The rearwardly curved shape enables the caregiver to approach the seat assembly 20 for insertion or removal of the child from the seat member 22 without interfering with or tripping over the front cross brace found on conventional infant swings.

[0014] The seat assembly 20 includes a moulded seat member 22 that is more particularly described US 7,422,284 filed on November 17, 2005, by Curtis M. Hartenstine, et al. The seat member 22 provides a support structure in which an infant can be placed and secured within the seat member 22 by conventional safety restraints (not shown) and permitted to reciprocally swing in a fore-and-aft direction. The seat member 22 is supported from the hanger housings 27, 28 by curved hangers 25 that connect with the seat member 22 and present a concave shape in a forward direction. As a result, the curvature of the hangers 25 contributes to the structure-free configuration beneath the hanger housings 27, 28, in addition to the mating curvatures of the front and rear legs 17, 15, to establish the open side configuration for access to the seat member 22.

[0015] As is best seen in Fig. 8, the structural members forming the front and rear legs 17, 15 are formed from an oval-shaped tubular member that provides a longer dimension in a direction parallel with the swinging movement of the seat assembly 12, depicted by the arrow 38, than in the direction perpendicular to the swinging movement of the seat assembly 12, represented by arrow 39. This oval-shaped cross-sectional configuration of the structural frame members provides a frame that is stronger in the resistance of the swinging motion than a frame having the same amount of material but formed in a conventional round cross-sectional configuration.

[0016] The transversely spaced hanger housings 27, 28 without any structural member interconnecting the upper distal ends of the rear legs 17 provides an open top configuration for the frame assembly 12, while the curved rear and front legs 15, 17, along with the curved hangers 25, provide an open side configuration for the frame assembly 12. Accordingly, the caregiver can access the child positioned in the seat member 22 from above, from in front, or from the side of the seat assembly 20 without interference from the frame assembly 12. These mating, curved shapes forming the frame assembly 12 establish an improved access, physically and visually, to the seat assembly 20 and any child positioned therein.

[0017] The mounting housing 30 mounted on the rear leg 17 on which the hanger housing 28 and the electric motor 29 are found is used to house an array of dry cell batteries 32 to provide power for operation of the electric motor 29. The placement of the battery array 32 at the connection of the front leg 17 with the curved rear leg 15 keeps the battery array 32 below the level of the head of the child positioned within the seat member 22, thus protecting the infant from possible injury from damaged batteries or from batteries that may be dropped onto the child seated in the seat member 22. The placement of the batteries 32 in the mounting housing 30 also enables the size of the hanger housing 28 in which the electric motor 29 resides to be smaller than if the batteries 32 were placed in the hanger housing 30 with the electric motor 29. Such geometry allows the two hanger housings 27, 28 to be sized similarly to provide an aesthetically pleasing frame structure.

[0018] The batteries 32 are mounted within individual compartments 33 having contacts 35, 36 arranged in series to provide electrical power for operating the electric motor 29 through wiring 37 that passes internally of the rear leg 15 to connect with the electric motor 29. A removable cover 31 retains the individual batteries 32 in their respective compartments 33 until replacement is required.
